Soldering in electronics is all about joining electronic components to the PCB by hand using soldering station or soldering iron, or wave soldering using wave soldering machine or reflow soldering using reflow machine. Soldering can be either hand soldering or automated soldering. It can also be either thru-hole soldering or SMT Soldering using Surface Mount Technology.

Hand Soldering in Electronics

Hand soldering is done for thru-hole electronic components using soldering iron or soldering station. Hand soldering is not meant for mass production. It is generally done for repairing and repair of rejected PCBs during mass production or for repairing of faulty Printed Circuit Boards after using electronic products for a long time.

Automated Soldering in Electronics

SMT Soldering in Electronics

SMD or surface mount electronic components (ICs and Chips) are soldered to the PCB using Surface Mount Technology. The process uses Reflow soldering machine and automated pick and place machines. Sometime repairing and replacement of SMD components is also done by hand.
